6 Claims.

This invention relates in general to fastener attaching machines such as are commonly used. .in securing buttons or fastener elements to garments or the like, and particularly to a kick-out and hold-down device adapted to be attached and operated with such machine to perform a prior operation on the garment before the fastener elements are attached thereto.

In the manufacture of certain classes of garments, and as a specific example we refer to the manufacture of overalls that customarily are provided with a large patch pocket attached -to the face of the bib, the upper end of the pocket ponent elements of a snap fastener device, and

then it is necessary to attach the complementary fastener element to the bib and in its proper alignment. In order to do this it is first necessary to remove the upper portion of a patch pocket from the setting station of the. fastener element on the bib.

Machines for accomplishing the above operation are known as'kick-out devices and one form is disclosed in the Huelster Patent No. 2,164,743. While'these former kick-out devices of the type disclosed in the Huelster patent were satisfactory for the purpose of moving a portion of the garment out of the path of the setting tool, they also had the fault of moving the garment out of alignment with its previously set This was due to the the operator was not strong enough to hold the garment against the kicking action of the kickout device and, therefore, a slight movement of the garment would cause the fastener part set on the garment to be misaligned or out of registry to its component element set on the pocket part. It is one of the objects of this invention to provide a device thatmay be easily attached to a fastener attaching machine and will operate in conjunction with the fastener setting mechanism, first mechanically to holdf'down the garment upon a support member and then kick out the'" overlying pocket portion out of line with the setting station of the machine.

With l this and other objects in view, this invention consists in the features, combination,

2 details of construction and arrangement of parts which will be first described in connection with the accompanying drawings and then more particularly pointed out in the specification.

In the drawings,

Fig. 1 is a side view of a fastener attaching machine showing the kick-out and hold-down device mounted thereon and in retracted position.

Fig. 2 is a plan View taken substantially along the line 2-2 of Fig. 1.

Fig. 3 is a left hand elevational view of the machine showing the hold-down and kick-out mechanism in their advanced position during the period of the fastener setting operation.

Fig. 4 is a front elevational view of the machine with the hold-down and kick-out mechanisms in their retracted position as shown in Fig. 1, and,

Fig. 5 is a sectional view to show the details of a hold-down device taken along the'line of 5-5 of Fig. 2.

It is to be understood that the machine to which this invention is applied may be either a button or snap fastener attaching machine, of well known construction. Such a machine consists essentially of a base or bed plate I!) having a curved standard II extending upwardly therefrom and supporting a bearing head If on its front end. A plunger I3 is slidably mounted in the head l2 and is operated at its upper endby a main oscillating lever is secured to and supported on a cross shaft 15 pivoting in spaced lug [5 extending upwardly from the standard H. The plunger I3 carries a setting die H having an element carrier block l8 mounted upon its lower end for receiving a fastener element such as an eyelet stud (9 (see Fig. 4). The stud I9 is held in line with the die by, spring op- .erated jaws 2i! pivoted in said carrier block and the stud may be fed from a hopper into the carrier block l8 through the usual form of feed chute not shown.

Mounted on the bed plate I0 is an anvil 2| supporting an element carrier block 22 on its upper end similar to the carrier block l8 carried by the rier block 22 preliminary to the fastener setting operation;

The garment illustrated as being operated upon by this machine may bean overall bib -26 to set a complemental fastener-element on. the;

bib part of the garment in line with the socket. 28, the position being indicated by the center line X in Fig. 1. The socket 28' will; of course, he complemental to the stud ['9 previously mentioned in connection with the plunger i3 and associated setting die I I. Inorder 1303591 the. few:

tener element upon the bib part of the garment at the position as indicated by the line- X it is, therefore, necessary to remove the overlying porof the patch pocket 21 sothat. the stud; [:9 and post 2 4 can be set upon the bib. 26 in the position of line- X with no. interference. It is, therefore, the purpose of the present. invention when applied to the above setting machine to first properly register the garment in the machine; cl-amp-the-garment against movement, and then remove the overlying portion of the bib from the setting station ahead of the descending plunger for setting the fastener elements;

In order to support the garment and properly register it preliminary to the fastener setting operation a platform table 30 'is provided that is held in elevated position substantially on a plane common withthe upper surface of the anvil car- 'rier block 22' and the feedtrack 25- as by means of support brackets 3 I attached to the bed plate l0. As noted in Fig. 2- thetable has a central cut-out 32 so as to circumvent the anvil= carrier block 22 and yet is close enough to said block to provide ample support for the garment in the area of the setting station. A pair of gauge fingers 33 are sl-id'ablymounted on horizontal rods 33aextending laterally from the-bearing head l-Z of the machine. The lower ends of the fingers 33 are formed with embossed portions 33b against which the upper end of the patch pocket 21- may be engaged for properly registering the garment relative to the setting station of the machine.

In order to hold the garment in the machine a clamping orpressermember 34 is provided and located substantially on the center line of the machine and behind the fastener set-ting station so as to prevent dislocation of the garment when the pocket kick-out members 35 and 36 are moved forwardly. The presser member- 34 is located between the pair of kick-out plates or members 35' and 36 of identical construction to' be more fully described later. The clampingmember 34 is made secure to a cross shaft 31' pivoted in the lower end of a pair of dependent bearing brackets 38 and 39 attached to opposite sides of the standard It. Oscillatingmotion is imparted tothe clamping member 34 through shaft 3! operated by a'lever 40 fixedly secured to the right end of the shaft 31, see Figs. 2 and 4. The free end of the lever 40 is connected to a cushion link 42 which specifically consists of two sections, an

upper section 43 and a lower-section 44. The upper section 43 is formed witha tubular end to telescopically'receive the lower section 44 the form of a rod. The lower'end of section 44 is formed with a yoke 45 connected'to the end of the lever 40 as by cross pin 41. The rod portion of the section 44 is formed with a reduced extension 48 that extends into a counterbore 49 of the upper section 43. A coil spring 5!! surrounds the reduced extension 48 to impart the cushion effect to the link 42. The cushion link 42 is provided to compensate for the variable thicknesses of the garments operated upon in allowing somesnze to the'clamo 'ns mem i r The-upper end of the cushion link 42 is connected to a bell crank lever 5| pivoted to the standard I l as at 52. Between the pivot point Shand, thepoint of connection with the link 42 the; belL crank 5 is provided with a cam follower roll 53 adapted to engage against the peripheral surface of a cam plate 54 fixedly secured to the right endofthe main cross shaft 15 as by set screw 55'. Rotation is imparted to the cross shaft t5; by of the main lever l4 and through the above described linkage operates the presser member 34 in proper timed relationship tothe working parts of the machine. The roller 53 is held; in constant; engagement with. the. face. of the cam plate 5'4 by. means. of a. coil spring 5.6 connected between the outer end of thebell crank lever 51 and'thestandard' .Hz.

Upon actuation of; the lever [:4 and; through. the above described mechanism the clamping ben 34 will be carried: down from its 11121 line position to the dotted position as shown .in-

1 where it. will clamp the bile partJ'ZB: ottheoverall againstthe upper faceot' the feed track- 25.

It i's'to. benoted that. the kick-out. plates 35 and 36 which straddle: the clamping member normal inactive position are as shown in line in 1, and in order to. operate these plates in the; act of removing the upper end of the patch pocket 21 they must necessarily be brought. down to the dotted position as shown in Fig. l. first motion of lowering the kickeouti plates is imparted thereto bymovement; of the clamping member 3d. This is accomplished: through the instrument of'a strong .leaf spring 58.that isimade secure to. the clamping member at its pointof attachment to the cross pin .31. The leaf spring 58 extends above and lengthwise of the clamp member in a free state and engages against; the topof' a cross bar-F291 thatjoins th-ekickeout plates together as an integral unit, as best seen in Fig. 5.. When the clamping member 34- is moved down to pressing position the spring 58 by its engagement with the cross bar 59 will resiliently impart the initial downward movement to the 'kiok ou't plates 35 and 38. V

The mechanism for operating the kick-out plates to advance the same forthe purpose of removing the overlying patch pocket located at the left side as best viewed in Fig. 3. It is to be noted from Figs. 1 and 3 thatv both kick-nut plates 35 and 36 are formed with cam slots 35a.

"and 33a of ofisetconflguration and slidablyem:-

braced the cross shaft 31 to. which the clamp member 34 is attached. The left. kick-out. plate 36 is operated from a bell crank lever 50 pivoted to. the standard H as at 6-1.. The lowerend of the bell crank is formed with an l ngated slot 62 engaging a stud 63 extending laterally from said kick-rout plat 36.- lhe pp siteend of th bell crank lever 60. supports. a. cam roller. that engages. against, the peripheral surface of a cam plate. Bifimdly attached to.- theopnosite. end of the main shaft. l5. as by set. screwv 56; similarto the cam plate 54. previously mentioned.

The bell crank Ellis normallytensioned ma clockwise direction to hold the rollerBA' against the camv plate. 65" and also retract. the kick-.out plates 35 and 3.8. by a. heavy coil sprmg fitc'cnseam nected between the bellcrank levertfl and the standard H. V H

In order to stabilize the cam plates 54 and til and provide a stronger connection between said 69 and 10.

Operation In the operation of attaching the fastener elements to the bib of an overall garment in line with a complemental element previously set to a patch pocket already attached to the bib, the garment when first brought to the machine will zbe properly oriented by the operator. For this .operation the bib will be laid on the support .table 30 with a considerable portion of said bib also resting upon the feed track 25. The upper edge of the patch pocket 21 will be brought into contact with the embossed ends 331) of the gauge fingers 33 and the edge seams of the patch pocket will be lined up with said gauge fingers which will thereby dispose the fastener element 28 on the patch pocket directly in line with the set ting station of the machine as indicated by the center line X.

When the garment is thus properly located with respect to the setting station of the machine the mechanism for operating the main lever 14 may be actuated to drive the plunger l3 and setting die I! downwardly. During the counter-clockwise movement of the main lever 14 as viewed in Fig. 1 both cams 54 and 65 will be carried therewith. This motion of the left cam 54 will first serve to swing the clamping or presser member 35 downwardly in a counter-clockwise direction as viewed in Fig. 1, and clamp the bib 26 against the upper surface of the feed track 25.

The counter-clockwise motion of the clamping member 3 1 will, through the medium of spring 59, also impart a pivoting action to the kick-out plates 35 and 36 about the pivot 31 and initially lower them to the dotted line position shown in Fig. 1. It will be noted that the front end of each of said plates 3'5 and 36 are formed with notches 35b and 361). This initially lowered position will bring the notches 35b and 36b of the kick-out plates in line with the upper edge of the patch pocket 21 and better serve to pick up the edge of the patch pocket. Continued movement of the main lever M and its attached cam 65 will actuate the bell crank lever fill on the left side of the machine and impart a positive advancing motion to both kick-out plates 35 and 36 which latter motion will cause the upper end of the patch pocket 21 to be moved toward the front edge of table 38, as shown in Fig. 3, out of line with the setting station of the machine. The forward substantially straight line motion of the kick-out plates 35 and 36 will be controlled by reason of the shape of the cam slots 35a and 36b in said plates which slots have sliding engagement on the support cross pin 31.

After the presser member 34 and kick-out plates 35 and 36 have performed their respective functions, continued motion of the lever it will cause the plunger is with its setting die El to complete its stroke and secure the fastener element (stud i9 and post 24) upon the bib part of the garment in its proper position to line up with the fastener element 28 on the patch pocket when the latter i returned to its normal position.
